Suppose that you choose the exponential distribution to fit the following data 2.4 0.5 0.3 1.4 0.9 0.7 1.2 1.6 6.9 4.1 You may readily check that the estimated parameter ? = 0.5 based on the maximum likelihood estimation. Now use K-S test with 5% significance level to conduct a goodness-of-fit test
QUESTION 5 In a goodness-of-fit test to see if a set of 100 values were randomly drawn from a normal distribution, the quartiles and median (i.e., the 0.25, 0.5, and 0.75 quantiles) for the normal distribution were used to determine intervals for sorting the data. What is the expected number of values that fall into each interval assuming the 100 numbers were drawn from the normal distribution? QUESTION 6 Consider again the goodness-of-fit described in the previous problem. Assuming that...
A random varible X taking values from [0,1] has Beta distribution of parameters a and B, which we denote by Beta(a,b), if it has PDF _f(a+B) fa-1(1 – X)B-1, fx(x) = T(a)l(B) where I(z) is the Euler Gamma function defined by I(z) = Sx2-1e-*dx. Bob has a coin with unknown probability of heads. Alice has the following Beta prior: A = Beta(2,3). Suppose that Bob gives Alice the data on = {x1,...,xn), which is the outcome of n indepen- dent...
1. Use golden-section search method with initial guesses of x = 0 and x=3 to minimize the following function: f(x)=10 exp(-x)+x? @ Don't use any computer program. Only a portable calculator is allowed. 2. Use parabolic interpolation method with initial guesses of x=0, x=1, and x3 = 3 to minimize the following function f(x)=10 exp(-x)+x? Don't use any computer program. Only a portable calculator is allowed. The minimum value of f(x)=10 exp(-x)+x is 1+In 30 = 4.401197... at x =...
